Title: Challenges of Engineering Education


1
Low Carbon Technologies for Energy Sector
Dr. V K Sethi , Director UIT, RGPV Bhopal

2
Sustained economic growth at 8 to 9 requires
that by the year 2012, we would need an installed
capacity over 2,00,000 MW and by 2050 at the
level of 10 Lakh MW i.e. a trillion or Terra
Watt This poses a Terra watt challenges for
India.
3
Major Contradictory ChallengesFaced by
Developing world
  • Quest for increased Generation capacity -
    Terawatt Challenge
  • Climate Change
  • - rising GHG level
  • Continued focus on coal based generation

4
Climate Change - rising GHG level
  • Green House Gas level rise from a current level
    of 390 ppm and consequent climate change,
    floods and draughts has affected 260 million
    people between 2000 and 2004 through natural
    calamities of these, 98 were in developing
    nations.
  • Developed countries with population of
    15 of world population have the share of CO2
    emissions at 50.
  • There is so much momentum in the system that
    we will certainly double CO2 level by end of
    the century.
  • Global temperature rise by 3 to 4 0C will
    cause displacement of over 330 million people
    in developing world.

5
  • World Green House inventory is over 29,000
    Million tones per annum (MTPA) with US over 20
    (India with total emission of about 1400 MTPA is
    only at 4.8 .)
  • Coal is going to remain main stay for power
    generation in at least next Three decades for
    India (92,157 MW Coal based generation out of
    1,43,311 MW total power installed capacity)

6
  • Therefore there is Global Tri-lima. The country
    is thus facing
  • Quest for increased generation.
  • Dependence on Coal based generation.
  • Climate change due to rising GHG level.
  • Solution lies in
  • Adoption of Green Power Technologies
  • Low Carbon/ No Carbon technologies Clean Coal
    Technologies
  • Development of Carbon capture Sequestration
    technologies

7
The Fourth Assessment Report of the
Intergovernmental Panel for Climate Change (IPCC)
has confirmed
  • The temperature of the earths surface has
    increased by 0.76C over the past century.
  • It is very likely (more than 90 probability)
    that most of this global warming was due to
    increased GHGs(green house gases ), resulting
    from human activity.
  • Eleven of the last 12 years (1995-2006) were
    among the 12 warmest years on the instrumental
    record of global surface temperature.
  • Mountain glaciers are receding and snow cover has
    declined in both the hemispheres.

8
The Fourth Assessment Report of the
Intergovernmental Panel for Climate Change (IPCC)
has also confirmed
The Fourth Assessment Report of the
Intergovernmental Panel for Climate Change (IPCC)
has also confirmed
  • Widespread decreases in glaciers and ice caps
    have contributed to sea level rise.
  • At continental, regional and oceans basin scales,
    numerous long term changes in climate have been
    observed. These include changes in Arctic
    temperatures and ice precipitation amount, ocean
    salinity, wind patterns, and aspects of extreme
    weather including droughts, heavy precipitation,
    heat waves, and the intensity of tropical
    cyclones.
  • Temperature is projected to increase further
    during the 21st century. The extent of change
    will be determined by how much more GHGs we
    introduce in the atmosphere. Best estimate
    regarding the future changes in climate by 2099
    for low scenario is 1.8 and for high scenario is
    4.0.

Energy for the Earth Planet- Some issues
  • World Generates 15 Terawatt of Energy (the US -
    about 3TW, India - 0.12 TW) today to support 10
    billion world population (Equivalent to230
    million barrels of oil /day)
  • By 2050 it is projected to need about 35 TW. Thus
    the world would need about 20 TW of non-CO2
    energy to stabilize CO2 in the atmosphere by mid
    century.
  • Among the non-CO2 options , it is possible that
    solar is the only one that can meet this Terawatt
    challenge and at the same time contribute to the
    reduction of climate change, with about 125,000
    TW of global incident sunlight.

17
Energy for the Earth Planet- Some issuesContd.
  • Key scenario for stabilizing CO2 in the
    atmosphere during 21st century turn on the
    viability of CO2 sequestration. This implies CO2
    capture, storage and then pumping to aquifers, to
    stay for millennia.
  • In any case minimum 10 TW is needed within a
    decade from Breeder Nuclear , CCTs and
    Renewables.
  • Biomass CO2 sequestration could also meet this
    challenge.

18
Prime Clean Coal Technology Options
  • Supercritical Power Plants
  • Integrated Gasification Combined
  • Cycle (IGCC) Power Plants
  • Circulating Fluidized Bed
  • Combustion (CFBC) Power Plants

19
Zero Emission Technology (ZET)

    challenge.

23
MAJOR TECHNOLOGICAL CHALLENGES
  • Technology Breakthroughs in areas like CO2
    capture Clean Coal Technologies
  • Low cost Solar Photo Voltaic Cells.
  • Energy efficiency on top of the agenda.
  • Carbon trading in all Major Industries.
  • Future funding in Clean Technologies.
  • Evolving Base line methodologies for variety of
    Green Clean technologies.

24
Green Energy solutions
  • Promote CCT in countries like India China
    where coal is main stay fuel for Power
    Generation.
  • Increased use of Advanced Fossil Fuel Technology
  • Energy Farming
  • Energy Efficiency
  • Major shift towards Green Technologies
  • Adoption of Renewable Energy Technologies in
    Rural Sector

25
Issues before the house
  • Technology break thoughts in the areas like CO2
    capture and Clean Coal Technologies
  • Development of low cost solar photo voltaic cells
  • Bringing Energy Efficiency Energy Conservation
    on the top of the National Agenda
  • Promotion of Carbon Trading on the strength of
    Energy Efficiency and Green Environment
    initiatives.

26
  • Energy conservation along with
    low-or-no- carbon energy sources is the key to
    dealing with the global warming problem.
  • All alternative sources such as Biomass,
    Geothermal, Tidal, Solar and Wind will meet
    only a quarter of projected demand for
    electricity by 2050 for supporting 10 billion
    world populations.
  • Though there are differing opinions of some
    technologists who favour nuclear fission, the
    only long term viable source of energy is thermo
    nuclear fusion. If there is any chance of
    Helium-3 fusion becoming a practical reality by
    2050, we must better start now.

27
  • There is serious under investment today in basic
    low carbon energy technologies such as
    photovoltaic materials for cost effective Solar
    Cells, membrane materials for better fuel cells
    and wide band-gap semiconductors for power
    electronics.
  • Capacity addition targets of no-carbon sources
    comprise of 6400 MW through Nuclear and 10700 MW
    through non-conventional sources by 2012. These
    are encouraging steps of Government of India.
  • Major thrust in CO2 reduction in long term and
    sustainable basis world came through adoption of
    advanced technologies of Coal utilization for
    power generation like Supercritical/
    Ultra-supercritical power cycle, Integrated
    Gasification Combined Cycle (IGCC), Fluidized bed
    combustion/Gasification and so on.

28
  • Revamping of old polluting power plants and
    achieving energy conversion efficiencies in the
    range of 40-45 by 2010 is the need of the hour.
  • India joined hands with global community of 16
    countries in RD efforts through Carbon
    Sequestration Leadership Forum (CSLF) in June
    2003 and signed the charter.

29
  • Indias position with regard to Carbon Capture
    Storage (CCS) is very clear. We dont make any
    commitment at this stage regarding deployment of
    CCS technologies. India advocates very strongly
    the Carbon Capture Sequestration.
  • Some of the demo pilot projects include.
  • - Pilot project on Geological CO2
    sequestration in basalt rock formation. The
    question of adoption of CCS will depend on this
    technology being cost effective.
  • -Projects under DST sponsored National Program
    on Carbon Sequestration (NPCS)

30
  • A Large number of projects are in different
    stages under NPCS through the country.
  • India has also joined Methane to Markets
    Partnership along with Argentina, Brazil, China,
    Columbia, Italy, Japan, Mexico, Nigeria, Russia,
    Ukraine, UK in November 2004, for
    Hydro- gasification of Coal Biomass
  • India has also collaborated with Canada, EU
    countries, Japan, China and south Korea in
    International Partnership for hydrogen Economy
    (IPHE) in November 2003.

31
  • US and India have signed the framework
    protocol during April 2006 in New Delhi, for
    the FutureGen project aiming to design
    develop built and operate first coal fired
    emission free power plant of 275 MW. A project
    involving IGCC CO2 capture.
  • The ITER- International Thermo Nuclear
    Experimental Reactor project is well on its way.

32
  • Pre-combustion de-carbonization is offering a
    promising technology for carbon capture. A
    typical example is coal gasification for
    production of synthetic Gas (Syn Gas) of CO and
    H2. This CO and H2 then react with steam to
    produce CO2 and H2. The CO2 can be saturated and
    H2 used in fuel cell.
  • Other options include Oxy fuel technology
    involving recycling of CO2 plus oxygen. Other
    options include IGCC, Supercritical and
    Underground coal mining which can reduce CO2
    emission through environmentally benign coal
    utilization for Power Generation.

33
  • Post combustion approach on an actual fossil fuel
    based Power Plant will be cost effective when CO2
    concentration is increased such as in an oxy fuel
    technology stated above. Likely options currently
    identifiable for CO2 separation and capture
    include
  • Chemical Physical absorption
  • Pressure swing and electrical swing absorption
  • Cryogenic Separation
  • Capture in fuel cell carbon Nano-tubes
  • Biochemical approach

34
RGTU INITIATIVES
  • Hybrid power plant of Wind, Solar Biomass has
    been setup which will pave way for sustainable
    power supply for variety of biomass fuels
    environment limitations.
  • Biomass Gasifier (10kW) Bio-diesel Plant (100
    LPD) has been commissioned
  • Green Energy Technology Center has been set up to
    focus on following areas
  • - Clean Coal Technology CDM
  • - Bio-fuels and bio-diesel
  • - Renewable Energy devices (hybrid)
    targeted to produce 1 MW Power for the campus
  • - Energy Conservation Management
  • - CO2 Sequestration CO2 capture
    technologies
  • .

35
The pilot plant at RGPV is one of the Carbon
Capture Sequestration plant together with CO2
conversion into Hydrogen, Methane Biodiesel
through Algae Route.

CO2 Sequestration Plant
37
A SUSTAINABLE POWER DEVELOPMENT MODEL FOR INDIA
  • Meeting Energy need of Rural India (about 100
    Billion Units per annum) through use of Renewable
    Energy technologies like Biomass, Wind, Solar and
    their Hybrid.
  • Use of Clean Coal Technologies (CCTs) Green
    Power Engineering (About 500 billion Units) for
    Mega Power Generation for Cities, Industries and
    all other sectors of economy.

38
Summary
  • Coal is going to remain our main stay in Power
    Scenario.
  • A synergy between Energy Environment is need of
    the day as over 56 GHG Emission is from Energy
    Generating Systems, for which
  • Accelerated growth of Power generation
    should be coupled with Environmental concern
    through adoption of Clean Coal Technologies
  • Renewable Energy Technologies need a fillip
    particularly for Rural Sector
  • Energy Conservation measures will go a
    long way in reducing Demand Supply Gap
  • ONCE THE PROJECT IS TAKEN UP UNDER CDM IT
    BECOMES SELF SUSTAINABLE.
